Unload the pdfstreamconverter on shutdown.

[brendandahl]

Hopefully one of the last review concerns.
"Your add-on now loads the PDFStreamConverter via Cu,import. Hence it should Cu.unload that module again during shutdown not only to avoid memory leaks, but also to avoid the previous version to be still loaded and used after updates."
